Question

The elements in Group 2A are known by what name? Consider the element with the electron configuration [Kr]5s^24d^7. What are the possible ions for this configuration? How many electrons are in the 4p orbitals of vanadium? Based on valence bond theory, what is the hybridization of the central atom(s) in C_2F_4? An _____ reaction results when the energy required to break bonds in the reactants is greater than the energy released by the formation of products. How many non-polar bonds does CH_3OH contain? What is the difference between a calcium atom and a calcium ion? What is the formal charge on sulfur in the best Lewis structure for the SCN^- (thiocyanate) ion? What is the formal charge on the oxygen atom in N_2O (the atomic order is N-N-O)? A chemist possesses KCl, PH_3 GeCl_4, H_2S, and CsF. Which of these compounds do not contain a covalent bond? What is a sigma bond? What is a pi bond? What are their basic differences? One electron is removed from O_2 and one from N_2. The bonding in O_2 is strengthened, while the bonding in N_2 is weakened. 1) Explain the findings using a MO diagram. 2) Predict what happens if an electron is removed from NO.

Explanation / Answer

Answer:

Question 1 :

The elements in Group 2A are known as alkaline earth metals.

The elements present in this group are beryllium(Be), magnesium(Mg),

Calcium(Ca), Strontium(Sr) , Barium(Ba) and Radium(Ra).

These are the elements present in group 2A.

These elements are grouped because they act similar properties.
